SPECIFICATION forming part of Letters Patent No. 649,420,dateci May 8, 1900.

Application filed September 2,1899. Serial No. 729,360. No model.)

To Mir/17mm may concern:

. Be it known that I, FRITZ BLINN, a citizen of the United States, residing at Turkey Hill, in the county of St. Clair and State of Illinois,

.5 have invented certain new and useful Impro vements in Oil-Hole Cleaners; and I do hereby declare the following to be a f ull,clear,

, and enact description of the invention, such as will enable others skilled in the art to ohwhichi i'tappertains to make and use the same. lily-invention relates to improvements in oil-hole cleaners; and it consists in the novel combination and arrangement of parts, as will be hereinafter more particularly dei scribed and claimed.

In the drawings, I ignreiI-"is a front elevation of my complete inrcntionas applied; to an ordinary bearing. Fig. 2 is a side eleva tion of the same, and Fig. 3 is an end view. The object of my inventionis to construct a simple,durable,and practical device for cleaning or removing the dirt or other foreign material contained in the oil-holes of bearings, and especially those employed in threshing and 25. farming machinery, as it is well known that such machinery is subjected to dirt and dust and that same finds its way into the oil-holes of the bearing, causing considerable annoyance; and the device consists of a'hand implementin the form of two spring-arms which can be readily pressed together and inserted into the hearing or oil-hole thereof, after which the said arms are compressed or brought together,collectin g and holding between them 5 the dirt .or foreign substance referred to, whereby the latter may be easily removed from the oil-hole of the bearing by holding said arms together until the implement is removed from the hearing. I

Referring to the drawings, 1 represents the hand implement above referred to, which is constructed of a single piece of metal, forming a spring connecting-loop 1, from which extends two spring-arms 2 of suitable length. 5 The lower ends of said arms 2 are rounded or curved, as shown at S, which are adapted to come in contact with the shaft a at the bottom of the oil-hole 5 of the hearing (3, and, as clearly shown in the drawings, the said arms.

are suitably depressed along their-length to a suitable distance, forming concave surfaces 7, which are adapted to receive and hold the foreign substance 8 contained within the oilhole 5, as clearly shown in Fig. 1. The opposite edges of each of the arms 2 where the same are depressed are provided with tapcr- 'ing edges 9, which operate to remove the foreign substance that adheres to the sides of the oil-hole in turning the implement after the same has been inserted into said hole.

In applying the implement the arms 2 are compressed sufficiently to permit the lower ends of the same to be inserted into the oilhole, after which the same is forced downwardly to the shaft 4 and then turned within '65 said oil-hole,in which operation all the foreign substance is cut away or removed from the sides of the said oil-hole, after which the arms 2 are further compressed holding the foreign substance between the same, and,while in this 7c position, removed from the oil-hole with the dirt or other foreignsubstancc between the lower endsof said arms.

Having fully described my invention, what I claim isv Au oil-hole cleaner, comprising a spring connecting-loop, two arms forming a continuation of the same, the lower ends of which are depressed forming two concave surfaces, at a suitable distance along their length, the 8r opposite edges of said arms being tapering along the depressed portions of the same, forming cutting edges, and the lower ends of said arms being rounded, as and for the pur pose described.

In testimony whereof I allix my in presence of two witnesses.
